To determine the force without doing a billion calculations, I used a scale to measure the force (in kg's). I put the magnets (arranged so they repel: north-south then south-north then north-south etc) in a tube and then capped one end. I put a dowel in the other end and pushed the magnets...
I am trying to calculate the forces between ten small cylindrical magnets stacked (inside a tube so they cannot flip/shift) so that consecutive magnets are repelling. The bottom magnet is attatched to the bottom of the tube with, let's say, the positive pole facing up. Then the second has a...
